Have there been any studies that explore how much generalization across contexts occurs with fear conditioning?
The "context" that the animal thinks it is in can be observed through the "map" that the hippocampal place cell network is using at a point in time. Different "contexts" have different "maps". This is known as global remapping. I might think that the conditioned fear response would only occur in situations for which there is no hippocampal remapping as compared to the original conditioned environment (i.e. the hippocampus is using the same "map" as the original conditioned environment).
Is there evidence supporting that assumption?
